SPECIFICATION forming part of Letters Patent No. 250,161, dated November29, 1881.

' Application filed April 19, 1881. (No model.)

To all whom 'it may concern:

'Be it known that I, .ALFRED W. MORGAN, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented a new and useful Adjustable Variable-Blast Tuyere-Iron forBlacksmiths, oi' which the following is a specification.

My invention relates to improvements in tuyere-irons in which arotatable center piece having different-sized radial nozzles operates inconjunction with a tuyere-iron case having a detachable head withtuyereholes above and a dirt-trap below; and the objects of my inventionare, first, to provide a tuyere-iron with an adjustable and variableconductor for the blast, by means of which a large fire for heavy workor a small one with an intense heat for small work may be kept up;second, to afford facilities for adjusting the variable-blast-conductor, to produce any size fire required; and, third, toprovide a means for discharging cinders and dirt from the tuyereironshell and dirt-trap below. These objects I accomplish by the mechanismillustrated in the accompanying drawings, in which- Figure l representsa vertical longitudinal section of the entire machine. Fig. 2 is an endelevation of the same. Fig. 3 is an elevation of the rotatableadjustable variable blastconductor; and Fig. 4 is a plan view of theindicator hand-wheel for operating the variable blast-conductor, showingthe spokes of various sizes corresponding with their respectivevarious-sized nozzles in the rotatable blastconductor.

Similar letters in the different views refer to like parts.

A represents a cylindrical case having an opening, w, in its vtop toreceive the tuyerehead B, also an opening, w', below, which forms aconnection wit-h the blast-pipe E at the side, and the dirt-chamber Fbelow. The dirt-chamber F has a hole, H, in its bottom, which is closedautomatically by the ball-valve Gr.

Inside of the cylindrical shell A is the rotatable adjustable variableblast-conductor O, which may be made with two or more nozzles. In thecase illustrated four nozzles are used,

radiating from the center. These nozzles are 5o constructed asshown-that is, the nozzle O is large enough to distribute `a blastthrough charge the air through the vtuyere-holes a2 a3,

and the nozzle G4 discharges the air only Ythrough the centertuyere-hole, a3. All the nozzles C C2 C3 C4 form branches of one com- 6oinon chamber, and the ends of the nozzles are turned in a lathe, so asto fit snugly within the case, yet loosely enough to permit theblastconductor to be turned freely for adjustment within said case. Thuswhen the nozzle G2 is w65 over the opening w of the case A the nozzle Ois free to discharge air through all the tuyereholes ofthe head B; butwhen the nozzle C is over the hole w,.then the nozzle (l2 discharges theair through the holes a a2 a3, as 7o before described. Thus as eachnozzle O C2 G3 G4 is brought opposite the tuyere-holes in the head B airis discharged relative to the size of the nozzle. Between the nozzles C2and O4 is a segment-rim, l), which, when adjusted over the hole w',forms a cut-off and permits the dirt and cinders which may accumulate inthe dust-chamber F to be discharged through the opening H when theyalveGr is raised and the blast applied through the pipe E. All 8o dirt whichmay fall into the cylinder A is wiped into the hole w' by the nozzles asthe blast-conductor is turned around. When the chamber F needs cleaning,the bali-valveG is raised and the dirt. blown out, as before described.f

The rotatable blast-conductor C has trunnions K K', one on each side,the trunnion K operating in a socket formed inthe solid head of thecylinder A, while the trunnion K', which 9o has a square hole, 7c, init, operates in the cylinder-head A. The cylinder-head A is secured tothe cylinder by bolts g g, made fast in the lugsff. The square rod;Jtitsjin the hole k of the trunnion K, also in the square hole I of theindicator-wheel L. The wheel L has spokes G5 C6 CFl O8. Each spokevaries in size to indicate the position of its respective nozzle.

Thus when the spoke G5 is turned up it indicates that the largest nozzle(lf is-in position under the tuyere-holes. The spoke U6 when turned upindicates that the nozzle C2 is under the tuyere-holes, and so on withthe other spokes and nozzles.

The head B may be a solid one with tuyereholes, or a waterjacket headhaving a chamber around the tuyere-holes to contain water, as shown inFig. 1, in which B represents the head, B the inlet for water, B2 theoutlet, and B3 the chamber surrounding the tuyereholes to contain water,for preventing the tuyere-head from burning.

What I claim as new, and desire to secure by Letters Patent, is-

l. Inatuyere-iron,thecylinderA, with blastpipe E and dust-chamber F,combined with the head A and bolts g g, substantially as shown anddescribed.

2. In a tuyere-iron, the cylinder A, combined with the rotatableadjustable variable blastconductor C and the headB, with tuyere-holes,

substantially as shown and described.

3. The rotatable adjustable variable blastconductor C, constructed withtrunnions K K and various-sized radiating nozzles, substantially asshown and described.

4. The rotatable adjustable variable blastconductor C, having asegment-rim D, between two nozzles, substantially as shown, for thepurpose specified.

5. The rotatable adjustable variable blastconductor C, having itstrunnions K, provided with a hole, k, combined with the rod J andindicator hand-Wheel L, having spokes C5 CG C7 C, of several sizes, eachsize spoke indicating the size of nozzle of the blast-conductor C whichis in line with it, substantially as shown and described.

6. 1n combination with the tuyere-iron case, consisting of the cylinderA, blast-pipe E, and dust-chamber F, the ball-valve G, the variableblast-conductor C, and head B, with tuyereholes a c a2 a3, substantiallyas shown and described.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.

ALFRED W. HORGAN.
